First make sure you have the little bearing #16 on #14. Line the teeth of 14 and 15 up. Then turn #15 till it pulls 14/16 tight against the back of #10. Put all your bolts back in make sure the slack is taken out of 15 still and put your clutch arm back on in the proper spot. If you don't take the slack all out, it will not let the clutch fully disengage. Even a tooth of slack will make it malfunction. The parts wear also and this has to be checked occasionnally if you start having that problem. Hope this solves your problem.
